Case studies

Our team of energy specialists are focusses on delivering energy and cost savings on the ground and not just on paper. We work very closely with our clients to understand nuances of the site, and also to ensure that our energy conservation schemes are understood by the engineering teams. We believe this is critical for the project's success as the site team has a key role to play during implementation and maintenance of the energy saving projects. 

We also coach teams on energy saving best practices to ensure that the energy and cost benefits are realised for years to come. The following case studies are illustrations to show you how we engage with the client through the entire process, and how we make impact happen on the ground. This approach is a unique proposition of UVKS, and a big reason for clients continuing to work with us.
